Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SF64G-TP are identified based on strict electrical and mechanical parameter compatibility. The primary substitution criteria are:

Critical Parameters for Substitution:

• Voltage - DC Reverse (Vr) (Max): Must equal 200 V
• Package / Case: Must be DO-201AD, Axial
• Mounting Type: Must be Through Hole
• Speed Classification: Must be Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: Must be ROHS3 Compliant

Secondary Parameters Allowing Variation:

• Current - Average Rectified (Io): Acceptable at 5 A or 6 A (5 A is acceptable as a lower-rated substitute)
• Reverse Recovery Time (trr): Acceptable within fast recovery range (35 ns or 50 ns)
• Forward Voltage (Vf): Minor variations acceptable within standard rectifier tolerances
• Operating Temperature Range: Extended ranges acceptable

Two substitute parts meet these criteria:

1. EGP51D-E3/C (Vishay General Semiconductor): Parametric substitute with 5 A rating (lower current capacity)
2. SF64GH (Taiwan Semiconductor Corporation): Parametric equivalent with identical 6 A rating and automotive qualification

Parameter Comparison

Engineering Selection Recommendations

SF64GH (Taiwan Semiconductor Corporation) is the primary parametric equivalent for the SF64G-TP. Both parts share identical electrical specifications: 200 V reverse voltage, 6 A average rectified current, 975 mV forward voltage at 6 A, and 35 ns reverse recovery time. Both operate across -55°C to 150°C junction temperature range and comply with RoHS3 standards. The SF64GH carries AEC-Q101 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Mechanical compatibility is confirmed through identical DO-201AD axial through-hole packaging.

EGP51D-E3/C (Vishay General Semiconductor) is a functional substitute with reduced current capacity (5 A versus 6 A). This part is suitable for applications where the 6 A rating of the SF64G-TP is not fully utilized. The EGP51D-E3/C operates across an extended temperature range (-65°C to 175°C) and maintains identical reverse voltage (200 V) and reverse leakage (5 µA @ 200 V) specifications. Reverse recovery time is 50 ns, within the fast recovery classification. RoHS3 compliance is confirmed. Selection of this substitute requires verification that circuit design accommodates the lower 5 A current rating.

Both substitute parts maintain full compliance with RoHS3 and REACH standards, ensuring regulatory continuity with the original SF64G-TP specification.

Frequently Asked Questions (FAQ)

Q: Can the EGP51D-E3/C replace the SF64G-TP in all applications?

A: The EGP51D-E3/C is a functional substitute with a lower average rectified current rating (5 A versus 6 A). It is suitable for applications where circuit current requirements do not exceed 5 A. Applications requiring the full 6 A capacity must use the SF64GH or the original SF64G-TP.

Q: What is the difference between the SF64GH and SF64G-TP?

A: The SF64GH and SF64G-TP are parametric equivalents with identical electrical specifications (200 V, 6 A, 975 mV forward voltage, 35 ns recovery time) and operating temperature range (-55°C to 150°C). The SF64GH carries AEC-Q101 automotive qualification. Both use DO-201AD axial through-hole packaging. The primary difference is manufacturer (Taiwan Semiconductor Corporation versus Micro Commercial Co) and automotive certification status.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use DO-201AD axial through-hole packaging with identical mechanical dimensions and pin configuration. PCB layout and footprint remain unchanged across SF64G-TP, EGP51D-E3/C, and SF64GH.

Q: Do the substitute parts meet the same compliance standards as the SF64G-TP?

A: Yes. Both EGP51D-E3/C and SF64GH are ROHS3 Compliant and REACH Unaffected, matching the compliance profile of the SF64G-TP.

Q: What is the significance of the reverse recovery time difference between SF64G-TP (35 ns) and EGP51D-E3/C (50 ns)?

A: Both parts are classified as Fast Recovery diodes with recovery times ≤ 500 ns for currents > 200 mA. The 35 ns specification of the SF64G-TP represents faster switching performance compared to the 50 ns of the EGP51D-E3/C. For applications sensitive to switching speed, the SF64GH (35 ns) or SF64G-TP should be selected over the EGP51D-E3/C.

Q: Which substitute part should be selected for automotive applications?

A: The SF64GH is qualified to AEC-Q101 automotive standards and is the recommended choice for automotive applications. The SF64G-TP and EGP51D-E3/C do not carry automotive qualification designations.

Q: Can the SF64G-TP be used in applications requiring extended temperature operation?

A: The SF64G-TP operates across -55°C to 150°C. For applications requiring extended temperature range, the EGP51D-E3/C (-65°C to 175°C) provides broader thermal coverage, provided the 5 A current rating is acceptable.
